Patent JP-H0246798-A (JP)
Title: Radio wave absorber
Inventor: ISOYAMA RYOICHI
IPC: H05K9/00
Filed: 1988-08-09
Abstract: PURPOSE:To obtain a ferrite tile-like wave absorber in which incident waves can stay for a longer period so that reflected waves can be reduced and which is reduced in weight so that working properties of manufacturing and fitting can be improved by forming two separated layers of woven fabric having a magnetic permeability different from that of the ferrite layer of the wave absorber in the ferrite layer with the ferrite being put in between. CONSTITUTION:Two separated layers 4A and 4B constituted of wove fabric of alumina are provided in a ferrite layer 2 with the ferrite in between. The phase of incident radio waves A is changed and the waves A are irregularly reflected when they pass through the layer 4A having a magnetic permeability different from that of the ferrite and further reflected and diffused at the boundary between the ferrite and the next layer 4B. Since the incident radio waves are repeatedly irregularly reflected and diffused at the boundaries between the ferrite and the first and second layers 4A and 4B of alumina fabric in such way, the staying period of the radio waves becomes longer and the quantity of finally reflected radio waves C is reduced.

Title: Production of narrow width metallic sheet
Inventor: TSUCHIDA YUTAKA
IPC: B22D11/06
Filed: 1986-08-25
Abstract: PURPOSE:To easily produce plural sheets of narrow-width metallic sheets having a required width at a low cost by preliminarily providing a required number of annular slit grooves in the circumferential direction to the barrel length part on the outside peripheral face of a cooling roll and drawing a molten metal in the form of bands while quickly cooling and solidifying the same. CONSTITUTION:The single roll 1 is rotated and the molten steel 3 housed in a pool 2 is drawn out in the form of bands while the molten metal is quickly cooled and solidified by the outside peripheral face 1a of the single roll 1. Since the slit grooves 4 are provided on the outside peripheral face 1a of the cooling roll 1, the molten steel 3 is quickly cooled and solidified on the outside peripheral face 1a while only the parts corresponding to the grooves 4 are easily cooled. Plural sheets of the narrow-width steel sheets 5 which are separated to the required width in the parts corresponding to the grooves 4 by thermal stress are obtd. The narrow-width cold rolled metallic sheets are thereby easily produced.

IPC: C21D9/573
Filed: 1987-08-07
Abstract: PURPOSE:To carry out cooling causing no coloring at the surface of a metal and requiring merely low cost of equipment, by bringing a reducing gas into contact with a metallic material in the course of bringing water into contact with the metallic material. CONSTITUTION:In the course of cooling a metallic material by bringing the metallic material into contact with water as a coolant, a reducing gas, such as CO and H2, is brought into contact with the metallic material.

Title: Manufacture of magnetic disk
Inventor: NIHEI NOBUYUKI
IPC: C09D175/00
Filed: 1984-09-21
Abstract: PURPOSE:To reduce curling and to also reduce output variation and separation loss by forming a magnetic layer on one surface of a flexible base and a back- coat layer on the other surface, specifying and controlling a roll-heating temperature, and puching it in a disk shape after calender treatment by a roll made of the same material.

If the heating temperature of the treating rolls 1 and 2 deviates beyond the range of 60-120 deg.C, or if the heating temperature control range exceeds + or -5 deg.C, it is difficult to eliminate curling sufficiently. Consequently, the manufacture magnetic disk is flat having every small curling and contacts a magnetic head nearly uniformly, and output variation and separation loss due to the curling of the magnetic disk are reduced.

Abstract: PURPOSE:To prevent the occurrence of dew condensation and reduce power consumption so as to be able to maintain comfortable air conditioning condition by a method wherein when an abnormal output from respective sensors measuring the temp. and relative humidity in a basement for living and of outside air is detected, an air conditioner is operated according to a control sequence dealing with this abnormal output. CONSTITUTION:A control part 10 into which measuring values from respective sensors 6, 7, 8, 9 placed at the inside and outside of a basement 1 are fed at all times is operated on the basis of these values. For instance, when room temp. is 15 deg.C, 22 deg.C, 27 deg.C respectively and the relative humidity in the room is 85% in all cases, the room temp. and the relative humidity are in a specified range and the control of humidity is necessary because of the high humidity in the room and the operation mode of an air conditioner is determined by the room temp. That is, the air conditioner is so controlled as to carry out space heating operation for a fixed time at a room temp. of 15 deg.C, dehumidifying operation at 22 deg.C, and space cooling operation at 27 deg.C. For instance, when the temp. sensor is short-circuited in the condition at a room temp. of 15 deg.C and a room humidity of 85% and its output becomes an abnormal temp. of 50 deg.C, the space heating operation before the trouble is carried out again.
